We established in the previous episode that two metals emerged across history and across cultures as the most suitable units of measuring value, ie, money. As promised there, let’s now look at the tussle between the two. Quite simply, silver is much cheaper than gold - given the dynamics of their availability for us to extract, and thus the relative scarcity of each. Even though we don’t these days trade in gold and silver, this is something we broadly recognize. Because of this, gold has generally enjoyed greater prestige, being used much more in jewelry and as a display of one’s wealth and status. Correspondingly, silver has had more value as a practical day-to-day transaction choice. (You may have been born with a silver spoon in your mouth but you soon grew up to flaunt your gold!) But yes, how much was the relative value of gold and silver? This of course varied over time, there being often other factors at play, but primarily it went back to the relative availability. But as, within a given society, the relative availability could vary, there was this constant game of trying to take advantage of the variation. The Good, The Bad, The Shifty To understand this, let me first mention what’s known in the field as Gresham’s law, which quite simply states that “bad money drives out good money”. Let’s say you have 10 coins of either metal, which can buy you certain amount of goods in the market. Now if you melt those coins, the bullion (or ingots or whatever way you’ve shaped them) has the same value as the face value of the coins. That’s good money. On the other hand, if the melted metal is valued less than the face value imprinted on the coins, then you have bad money. It’s not hard to see how tempting it can be for governments to issue ‘bad money’, it means it would cost them less to mint those coins - this topic, debasement is juicy on its own, so I’ll reserve it for an episode in the near future. Under the same logic, governments would never want to denominate coins at face value lower than commodity value. Because what would you do if the face value of those 10 coins were lower than their price in weight? You’d melt them, you’d hoard them, these coins would disappear from circulation. Now let’s take a real-world historical example of one case of how this panned out specifically in the battle between the two metals - there are several such cases, but we have to pick one. Elements of Surprise In 1717, the ‘Master of the Mint’ in Royal Mint, Britain’s official coin-issuer, made a fateful move. He set the price of roughly one part of gold to 15 parts of silver. (I’m quoting rough figures here to keep the math simple.) However, in Continental Europe, it cost 14.5 parts of silver to buy one part of gold. Again, let’s see how this works out. Essentially what this meant was gold was artificially overvalued by the Mint relative to silver, whereas on the Continent, silver fetched more gold. So what would I do, I’d scoop up all the silver I could get hold of, make a trip across the English Channel, and, given silver buys more there and gold is cheaper, buy up all the gold I could for my silver and bring that gold back to Britain. What would I do once I’m back home? (After having a cup a tea, of course!) I’d buy up all the silver I can for that gold, because, that gold buys more silver in jolly old Blighty! And then... time for another trip to the Continent (Only delayed if the weather report reads “Fog in the Channel, Continent cut off”) The consequence of this was that soon all the silver disappeared from Britain, and a lot of gold flowed in, inadvertently pushing Britain, with eventually wider consequences beyond the island, onto a de facto gold standard! We would wonder who the hell was this guy who couldn’t even calculate the relative worths of gold and silver? Well, it was none other than Sir Isaac Newton! Yes, Newton! I mean, in the midst of writing his great work that essentially defined modern physics, we can say he took a break to invent a new branch of mathematics, Calculus, because the existing system didn’t allow him adequate expressiveness and precision! Unbeknownst to most of us, Newton in fact had his finger in many different pies, and in the latter years of his life he took on this role at the Mint as mentioned. To be fair to the great master, he did point out the problem, but the government did not bother to fix it, presumably underestimating the power of Gresham’s law. Furthermore, for Newton’s own legacy, the yet other element of irony is that, and again this may surprise many, he spent many years of his life trying to crack alchemy -- which was typically the attempt to turn lead to gold, he was essentially obsessed with alchemy. While the promise of alchemy was elusive to him as to anyone else, did he end up in real life with some sort of mathematical alchemy ‘turning silver to gold’? So yes, economics, as an intersection of mathematics and human psychology has its ways! The man who described the laws of physics couldn’t defy the physics of money, Newton defined gravity but could not defeat Gresham!
